FAQ
Frequently asked questions
How do I convert WAV to MP3?+
Upload your WAV file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the MP3. There is nothing to install and no account required.
Is converting WAV to MP3 free?+
Yes. WAV to MP3 conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the MP3 keep the quality of my WAV?+
StandardsPDF aims for the highest fidelity the MP3 format allows, so your audio file comes through looking as close to the original as possible. Some format-specific details may adapt where MP3 works differently to WAV.
Can I choose the bitrate when converting WAV to MP3?+
On the free tier StandardsPDF picks a clean default bitrate for your MP3; Pro lets you set the exact bitrate and sample rate for the WAV to MP3 conversion.
What is the maximum WAV file size I can convert to MP3?+
Up to 100 MB per WAV on the free tier and 2 GB on Pro. If your WAV is larger, split it first or upgrade for the higher limit.
Can I convert several WAV files to MP3 at once?+
Yes – add multiple WAV files and StandardsPDF processes them as a batch, returning a MP3 for each.
Can I convert WAV to MP3 on my phone?+
Yes – the WAV to MP3 converter is fully responsive and works in Safari, Chrome and other modern browsers on iOS, Android and iPadOS.
How long does a WAV to MP3 conversion take?+
Most WAV files convert to MP3 in a few seconds. Larger or higher-resolution files take a little longer, but there is never a queue on the free tier.
